[Skimmertalk] 192 vs. 96 Khz on QS1R

[N4ZR]

That sounds like some sort of bottleneck, perhaps in data getting to 
Skimsrv.  Have you looked closely at the USB traffic to see if things 
are being dropped?  I saw something similar when comparing two RPs, 
though of course the architecture is different.  In my case, the issue 
was Ethernet between the RPs and the computer.  Got a 20-buck Netgear 
Gigabit Ethernet switch and that's a thing of the past.

I've also noticed disparities between what one radio copies and what the 
other does.  Aside from the difference in radios, which appears to be 
very small, at least in terms of SNR, I suspect this may result from 
starting the two Skimsrvs at different times, somehow causing decode 
performance differences.  Here, I've noticed that my QS1R and RP-16 (the 
new one) seem to converge when they have been running for a relatively 
long time
